Hello! I was curious if it is possible to have mapserver bilinearly upsample a low resolution raster to a higher resolution when there is no reprojection required.
My setup is that I have a very low resolution image (a bathymetric layer) and a much higher resolution image (aerial), both in web mercator. When I request a high resolution XYZ tile, the low resolution image remains pixelated (it looks as if its is nearest neighbor upsampled) at the raster's native resolution even though I have set in the PROCESSING directive RESAMPLE=BILINEAR. I suspect from the docs that RESAMPLE only comes into play when we're doing on-the-fly reprojection, is that correct? When no reprojection is required, but just simpler upsampling, can one change the kernel used? Many thanks! Patrick
